To all wlwm alt may concern:

Be it known that 1, Hanvnr H. Mona,

residing at Missoula, in. the county of Misssonlaand State of Montana,have invented castings is the reach member 7 that is formed of two 4X6timbers, the outer ends certain new and usefulv Improvements inSled-Couplings, of which the following is a specification.

My invention, which generally relates to improvements in bob or loggingsleds,

more specifically comprehends a new and improved construction of partsespecially designed for coupling the front and back sled members thatefitectively serves to hold the said sled members coupled under allordinary conditions of travel and u' 'hereby the beams of the front andbind sleighs are perfectly free and each sleigh independent of the otherand in which the coupling devices are particularly constructed andarranged so" that they may be quickly lifted oil and disconnected fromthe front and rear sleds and put onto other sleds, in case those fromwhich they are removed are broken or disabled.

lVith other objects in View that will hereinafter appear, my inventionconsistsin certain details of construction, and peculiar combination ofparts all of which will be hereinafter fully described, specificallypointed out in the appended claims and illustrated in the accompanyingdrawings, in which:

Figure 1, is a plan view of my invention. Fig. 2, is a side elevationthereof, partly in section. Fig. 3, is a transverse section taken on theline 3 3 of Fig. 2. Fig. i, is an enlarged detail central verticallongitudinal section, showing the manner of connecting the tongue to thecoupling member.

In the practical application of my invention, the front and rear sleds,designated A and B, may in the general contour be of any approved type.In the present drawing they each consist. of the oppositely disposedrunners a-a and b-?) that are joined by the cross beams 12, the outerends of each of which are fixedly held by the strap bands 1020, and theangle plates 21 as best shown in Fig.

3 designates a cross bar that transversely joins the front ends of therear sled runners, the ends being reduced to form bolts to receive clamnuts 30'-30.

On each sleigh beam, centrally thereof, is mounted a beam castin, 5, inthe nature of a rectangular hollow ody that on top of the beams, each ofsaid castings being held 'by a sing-lo lain-g bolt 6 that extendstlirong h the sleigh beam or bolster.

Freely slidable through the two hollow in the reach member and as theypass down into the cross beams, hence the two beams are perfectly freefor movement independently of each other and furthermore the draft orreach member is sl-idable backwardl-y or forwardly by the draft strainsthereon independent of the back or forward movement of the sleds.

The bar 4 on the rear sled is connected by i tho flexible' or crossedchains 9 9, the rear ends of which are linked to the opposite ends ofthe cross bar 4, the front ends being linked to the cross beam- 2 of'thefront sleigh.

The cross bar 3 of the front sleigh has a draft or coupling member 12 tothe rear end of which is connected a draw head 13, hav ing shank 13 of asize to freely slide between the outer ends of the timbers 7-7 and theend cap plates thereon, and the said draw-head has the usual apertures13 for the coupling pin and in the present case its rear end isapertured to receive a buffer bolt 14, that has a head 14* for coactingwith the butter spring 15, that fits around the bolt 14 back of itshead. The outer end of the bolt 1-! passes through the aperturcd end ofa substantially U-shaped clevis, secured between the members 7--7 andthe said end has a slot 14 to receive a key 16,, as clearly shown inFig. 4, from which it will be readily apparent that by reason of connecting the draw-head to the clevis and the clevis to the draft or reachmember, the spring 15 acts as a buffer when the drawhead pulls forwardlyor backwardly.

To the front and to the rear ends of the coupling member 12 are fastenedstra irons 18-18 that take over the upper ant, lower face of the ends ofthe said member 12 to which they are secured by aolts and nuts, andwhose outer ends are e-Xtended to form coupling members 18 the saidmembers having elongated slots, as at 18*, to f0rm, as'it were, thelinks for coa'ctingwith the coupling pin.

3 designates the front cross bar for the front sled runners, that has atongue 3 that rojects forwardly under the coupling memequipped with acoupling or draw head constructed exactly similar to the draw-head at rof parts as shown and described any the other end.

[From the foregoing description taken in connection with theaccompanying drawings it is'believed the. complete construction, ad-

wanta es and the manner in which" my con- I struction of bob or loggingsled may be used will be readily understood.

By reason of providing the arrangement desired number of sleds may becoupled together and in such manner as to provide a simple means forpulling them and with 'theii loads evenly distributed.

What I claim is:

' 1. As an improvement in' logging sleds, the combination of a front anda rear bob, each includin a transverse beam, a hollow casting pivota lybolted to each of said beams,

mit assa'ge of the casting bolt, and crossed beam, a hollow castin a"reach member sl-idable through said castings and having a longitudinalslot to perflexi le connections between said bobs, substantially asshown and described.

2. As an im rovement in logging on other I sleds, the com ination of afront and a rear bob, each including a transverse beam, a flat hollowcasting mounted on each of the trans- 45 verse beams, a king boltconnection for each casting for removabl-y securing the same on thetransverse beams, a reachbar slidable' in the castings, said bar havinga draw-head at each end and the forward bob having a 5 draft tongue asset forth.

'3. The combination with the front and rear bobs relativelyindepe'ndently'mdvable,, each of said bobs including a transverseremovaloly supported on each of sai beams central y thereof, a drafttongue connected to the' front bob, and flexible members that jo'in'thei rear bob to the front bob; of the reach member slidably held inthe hollow castings, a buffer drawhead mounted on each end of the saidmember, and a coupling bar having strap irons on each end, shaped toform links for coactin with the coupling pins of the drawhead, a] beingarrangedsubstam 5 tially as shown and for the purposes described.
